Answer:
There will be an extra chromosome on the 21st chromosome.
Explanation:
Down syndrome (aka trisomy 21) is a genetic chromosome 21 disorder causing developmental and intellectual delays. Karyotypes show the chromosomes so the 21st chromosome will be abnormal.

How would the way I dress be impacted if photosynthesis stopped tomorrow?
write half a page for full credit
thank you you're a lifesaver
Answer:
i dont want to do so much writing but i guess i will help
Explanation:
If photosynthesis came to an abrupt end, most plants would die within short order. Although they could hold out for a few days -- or in some cases, a few weeks -- how long they lived would largely be a factor of how much sugar they had stored within their cells. Large trees, for example, may be able to soldier on for several years — perhaps even a few decades — because of their energy stores and the slow rate of use. However, the majority of plants would meet a withering end, and so would the animals that rely on them for nourishment. With all the herbivores dead, the omnivores and carnivores would soon follow. Although these meat-eaters could feed on all the carcasses strewn about, that supply wouldn't last more than a few days. Then the animals that temporarily relied on them for sustenance would die.
What role do cell membranes and protocells play in the "RNA" world?
Answer:
reibosome
Explanation:
Reibosome is a large molecular complex that assmebles proteins.
Role of Cell membranes and Protocells:
Messenger RNA (mRNA) carries the protein blueprint from a cell's DNA to its ribosomes, which are the "machines" that drive protein synthesis. Transfer RNA (tRNA) then carries the appropriate amino acids into the ribosome for inclusion in the new protein.Protocells are thought to have facilitated the reproduction of RNA and therefore the exchange of genetic information at a time before the advent of DNA and proteins.Learn more:

Three bird species share a habitat Bird A eats insects and plant seeds. Bird B drinks flower nectar. Bird C eats plant seeds. A drought occurs in their habitat, and that season's plants are wiped out entirely. What is the likely outcome for each type of bird?
O Bird B survives, either bird A or bird C dies, and the other survives.
O Bird A survives, both birds B and C die.
o Bird A survives, either bird B or bird C dies, and the other survives.
O Bird B survives, both birds A and C die.
Answer:
Bird A survives and both b and c die
Explanation:
Hi! hopes this help :)
Three bird species share a habitat Bird A eats insects and plants seeds. Bird B drinks flower nectar. Bird C eats plant seeds. Drought occurs in their habitat, and that season's plants are wiped out entirely under this condition only Bird A survives, both birds B and C die due to the condition of resource scarcity.
What is resource scarcity?In the ecology, resource scarcity was mainly represented by the two factors that are food and water which are primary resources for survival if anyone one resource is not available for the bird species it will affect its survival.
Therefore, due to the resource scarcity only Bird A survives, both birds B and C die.

Answer:
Explanation:
first is meiosis, second is h. chromosomes, third is chiastsa, fourth is variation, and fifth is exchange
Answer:
The tight pairing of the homologous chromosomes is called synapsis. In synapsis, the genes on the chromatids of the homologous chromosomes are aligned with each other. The synaptonemal complex also supports the exchange of chromosomal segments between non-sister homologous chromatids in a process called crossing over.

What happens to the cell’s genetic information during the cell cycle?
Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️

How is the production of NADPH useful for the process of photosynthesis?
The Calvin cycle is maintained and powered by the NADPH generated during the light-dependent stage of photosynthesis.
What is the role of NADPH is the photosynthesis?From the thylakoid to the stroma, NADPH moves. It is a high-energy electron carrier that transports both high-energy electrons and the hydrogen needed to make sugar.
NADPH will go to the Calvin cycle, where its electrons will be used to convert carbon dioxide into carbohydrates. ATP is the other component required by the Calvin cycle, and the light reactions also supply this.
NADPH is created during photosynthesis by using light energy in the chloroplasts' electron transport chain.
The Calvin cycle and subsequent processes that result in the production of carbohydrates can subsequently utilize it as a form of energy currency.
Therefore, the production of NADPH useful for the process of photosynthesis.

What are the new cells called and how do they compare with each other?
Answer:
The original cell is called the mother cell and the two new cells are called daughter cells.
Explanation:
The mitotic (M) phase and cytokinesis (C phase) together are called cell division, the division of the parent cell (original) into two daughter cells (new cells), each with the same genetic information (chromosomes) as the parent cell. Mitosis does NOT occur in prokaryotic cells that do NOT have a nucleus. (tesd. net)
The nucleus divides during mitosis, while the cytoplasm divides during cytokinesis. The two new cells are referred to as daughter cells.
What is daughter cells?Diploid cells are the daughter cells of mitosis. Diploid cells have two complete chromosome sets. Mitosis creates no genetic diversity in normal healthy cells because the daughter cells have exact copies of their parent cell's DNA. Either of the two cells formed when a cell divides through mitosis. Because they have the same number and type of chromosomes as the parent cell, daughter cells are genetically identical. Daughter cells are formed by the division of a single parent cell. They are produced by the mitotic and meiotic division processes. Cell division is the reproductive mechanism that allows living organisms to grow, develop, and reproduce.To learn more about daughter cells, refer to:

Monosaccharides can be grouped as aldehydes and kefone groups,what is their difference and similarities and list four examples for both of them
Answer:
Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
Explanation:
Similarity
Both the aldehyde and ketone have C=O group
Difference
In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO
while in ketone the function group is C=O only that is bonded to two carbon atoms.
Example
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
